Reverse indiglo gauges

Does anyone know how to fasten the gauges to the Factory ones? The instructions said to put them over the stock ones but they don't stay in place. Do I glue them or something? Any help would be greatly appreciated.
Thanks

they should have punched holes for the screws on the mph and rpm to hold them. the fuel/temp will need double sided tape. This can ruin them if you later decide they are rice/ugly and its not a good idea to replace your cluster...the odometr reading will be wrong and it will devaluate your car.

do yourself a favor and sell them
